My wife has been vegetarian for about 2 years, and though I am not one myself, I have significantly reduced my meat consumption by probably 80% since the start of the pandemic when prices skyrocketed and meat availability at stores was low. At home, I eat only meatless meals as it's easier to just make one dinner for both of us. Occasionally (like today), I'll smoke a pork butt or brisket that I'll vacuum seal and freeze for work lunches in the future. Right now, I have a pork butt, some tofu, and seitan on the smoker.
I don't have so many specific recipes as I do substitutions and ideas for meatless versions of meals that might traditionally contain meat. I'll typically look at meals we used to eat, and substitute a meatless substitute for the protein in the recipe.
Seitan is a very versatile meat substitute you can make yourself, flavor and cook to your liking. I currently use it as a chicken substitute for boneless wings/nuggets, or chicken pieces in a stir fry or dishes like orange chicken, etc. It also makes a good substitute for beef like you would find in Chinese cuisine, and for making meatless sausages. I've also seen recipes for seitan smoked brisket, seitan turkey, and seitan corned beef/pastrami for reubens. That's something I'll tinker with over the winter.
Tofu is an interesting one. I've never found it to be a great direct meat substitute, though it's great for adding some protein and texture to dishes like a stir fry. It takes the place of pork quite well when used in small pieces for things like char siu for fried rice. My favorite thing to do with tofu is make a meatless pepperoni for pizza topping.
There's tons of different brands of meatless/plant-based alternatives in grocery stores now. Beyond's breakfast sausage patties make a great breakfast side, good in a breakfast sandwich, and I've even made sausage gravy for biscuits with them. Their sausage links are a great substitute for bratwurst. Impossible just released their own sausage which looks promising but I haven't been able to try it yet.
For a ground beef substitute, I find Impossible to be a great one. It works very well for burgers, meatballs, meatloaf, as crumbles in a lasagna, crunchwraps/taco/burrito, (ground) philly cheesesteaks, etc. It cooks very similarly to ground beef, browns very similarly, and holds together well. I find Beyond's version to be strange and a bit offputting.
Jackfruit is a popular one that can easily replicate pulled pork.
Gardein and Quorn both make great nuggets, meatless crumbles (ground beef-ish), chicken strips, and a few other things. Morningstar's veggie hot dogs are pretty good, and I believe I liked their nuggets as well. I've never had anything from Lightlife that was remotely edible, so I'd avoid them.
Soy curls and tofu skin/beancurd sheet are two substitutes that I've not had the opportunity to try, though I'd love to. I've seen Philly cheesesteaks made with soy curls, and sandwiches replicating Arby's roast beef using the beancurd sheets.
I've never found a meatless bacon that I enjoyed, but when I was making rice paper bacon one night, my wife took some of the bacon flavoring I'd mixed up and mixed that with some mayonnaise, essentially making a "bacon" mayonnaise. We love it! We have BLT's with just that mayo, lettuce, and tomato.
And of course, there's plenty of things you can make with rice, lentils, many different kinds of beans, chickpeas, etc.
